Generally, its hard to visualise the gap between sensor sizes purely by reading through a spec sheet. The image below will offer you a far better sense of the sensor measurements in the E70 and RX10.

Clearly, both of the cameras have different resolutions and different sensor sizes. The E70 due to its tinier sensor will make getting bokeh trickier and the Sony RX10 will give more detail as a result of its extra 10 Megapixels. Greater resolution will also let you crop images a bit more aggressively. The more aged E70 is going to be disadvantaged in sensor technology.
